Scott Nixon

AI platform engineer. Infrastructure operator. Builder of PAS CLI and Reckoner.

I combine 20+ years of infrastructure and startup experience with current enterprise AI work at Citi. My focus: LLM-powered developer systems that plan, delegate, test, and open pull requests with real verification gates.
